Q: I have over 300 domains. Do I have to pay $35 per month for each domain?

A: No. iBlock charges per million emails processed. You can have an unlimited number of domains in your account.

Q: What happens to my email if my mail server breaks or my Internet connection goes down?

A: Your email will queue up on our server cluster until your mail server comes back online. No email will be lost or returned.

Q: How can your mail server handle all of this mail?

A: We operate server clusters that will scale to hundreds of servers. Multiple mail servers are load balanced behind a Cisco Local Director. This appears as one server to the outside world, but is actually many servers.

Q: How long will my mail get delayed using this service?

A: The delay depends on many factors including how busy our servers are, how busy your mail server is, and how large the email is. Emails with large attachments take longer to virus scan. The average delay is typically less than one second.

Q: I operate a web hosting company. Can I resell this service to my customers?

A: Yes. You can resell the service. In fact, if you are subscribed to the professional service you can give each of your domain customers their own iBlock administrative account.

Q: What makes iBlock better than other managed services?

A: iBlock uses the same spam blocking techniques as other managed services and also uses a proprietary blocking method that accounts for its high success rate.

Q: How does iBlocks proprietary method work?

A: We could tell you but then we'd have to kill you! After much research, we've discovered a revolutionary way to block spam and we're not telling anyone. This is why we only offer iBlock as a managed service. Once spammers discover how spam is iBlocked they'll work on a method to get around it.

Q: What if some of my domain users don't what their email filtered?

A: If you add the email addresses to the non-subscriber list, those users will only have their email scanned for viruses.

Q: How will I know if iBlock is filtering my mail?

A: If you look at your email headers they will show that they passed through one of our filtering servers. You can also see detailed graphs and lists of emails that have been blocked and why they were blocked by logging into the iBlock web interface.

Q: Can I customize the iBlock login screen?

A: Not currently. You can log in at http://iblock.ispservices.com or we can add an alias for your domain users to log in with. For example: If your domain is www.myisp.com, we could set up http://iblock.myisp.com or some other name that you choose.

Q: What if your filters are blocking mail from someone that I want to receive mail from?

A: You can white-list any user or domain. For example: If one of your users can't receive mail from an ISP who is being blocked you could add that ISPs domain or just that ISPs users email address to your white-list. My customer can't get mail from john@blockedisp.com. You can white-list john@blockedisp.com or the entire ISP blockedisp.com.
